Jonquel Orthea Jones (born January 5, 1994) is a Bahamian professional basketball player for the New York Liberty of the Women's National Basketball Association (WNBA). She was drafted with the sixth overall pick in the 2016 WNBA draft. Since May 2019, she also holds the citizenship of Bosnia and Herzegovina, allowing her to play for the national team.

A 6'6" power forward/center, Jones played college basketball for Clemson and George Washington. After the February 2022 Russian invasion of Ukraine, she left the Russian team UMMC Ekaterinburg, and joined the Turkish team Çukurova Basketbol.

In 2016, Jones was acquired by the Connecticut Sun after having her draft rights traded by the Los Angeles Sparks in exchange for Chelsea Gray and two draft picks. In her rookie season, Jones was the backup center for the Sun. She averaged 6.8 ppg, 3.7 rpg and 1.1 bpg in 34 games with 6 starts.

In 2017, Jones became the starting center for the Sun and had a breakout second season. After an 0–4 start, Jones led the Sun to their first win of the season, scoring 23 points along with 21 rebounds in a 97–79 win over the Chicago Sky, making her the 13th player in league history to record a 20-point, 20-rebound performance. On July 8, Jones scored a team-high 22 points and 9 rebounds as the Sun completed the biggest comeback in franchise history, defeating the Washington Mystics 96–92 after overcoming a 22-point deficit. Jones was selected to the 2017 WNBA All-Star Game, her first career All-Star Game appearance. She finished the season averaging a double-double in points and rebounds and also averaged career-highs in scoring, rebounding, and blocks. She broke the single season record for rebounds with 403, breaking Tina Charles previous record of 398 (the record would be broken again by Sylvia Fowles in 2018). Jones was selected to the 2017 WNBA All-Star Game and received the WNBA Most Improved Player Award. Her breakout performance, along with teammates Jasmine Thomas and Alyssa Thomas emerging as All-Stars, led the Sun to the playoffs as the fourth-seeded team. They received a bye to the second-round elimination game, where Jones scored 19 points and grabbed 15 rebounds in an 88–83 loss to the number 5-seeded Phoenix Mercury.

In 2018, Jones would have a reduced role on the team despite her success from last season. She started in 16 of the 34 games played but would still effective for the Sun both in the starting lineup and off the bench. By the end of the season, Jones won the WNBA Sixth Woman of the Year award. The Sun made it back to the playoffs as the number 4 seed with a 21–13 record, receiving a bye to the second round. However the Sun would lose yet again to the Phoenix Mercury in the second round elimination game by a final score of 96–86.

In 2019, Jones would redeem her starting Center role for the whole season. She would lead the league in rebounds once again and averaged a career-high in blocks, steals and minutes by the end of the season. Jones was also voted into the 2019 WNBA All-Star Game, making it her second all-star appearance and would also make WNBA Second Team. The Sun were a championship contender in the league, finishing with a 23–11 record and the number 2 seed, receiving a double bye to the semi-finals. In the semi-finals, the Sun swept the Los Angeles Sparks 3–0 to advance to the WNBA Finals, making it the franchise's first Finals appearance since 2005, and Jones' first career Finals appearance. The WNBA Finals series was a hard-fought battle, but the Sun fell to the Washington Mystics in five games.

In June 2020, Jones announced that she would sit out the WNBA season due to the COVID-19 pandemic.
